چکیده
|
The aim of this research is to investigate the viscoelastic behavior and determination of crosslink density of thin conductive coatings of urethane acrylatepolyaniline. for this purpose, polyaniline and urethane acrylate resin were synthesized. nanocomposites with different percentages of polyaniline (1, 3, and 5%) were prepared and cured by ultraviolet irradiation. the viscoelastic properties of prepared thin films were evaluated by dynamic mechanical thermal analysis under stresses with a certain frequency at different temperatures. also, crosslink density of nanocomposites was measured after ultraviolet curing. the results indicated that the glass transition temperature decreases and the crosslink density increases with the amount of polyaniline.
